BACKGROUND OF THE INVENTION Field of Invention

This invention relates to an ingestible drug delivery device configured for wireless communication with other ingestible drug delivery devices.

According to the CDC, a poisoning occurs when a person's exposure to a natural or manmade substance has an undesirable effect. A drug poisoning occurs when that substance is an illegal, prescription, or over-the-counter drug. Most fatal poisonings in the United States result from drug poisoning.

Poisoning can be classified as:

-   -   self-harm or suicide when the person wants to harm himself;     -   assault or homicide when the person wants to harm another; and     -   Unintentional, also known as “accidental,” when no harm is         intended. Unintentional drug poisoning includes drug overdoses         resulting from drug misuse, drug abuse, and taking too much of a         drug for medical reasons.

Drug overdose death rates in the United States have never been higher. Drug overdose death rates have risen steadily in the United States since 1970.

-   -   In 2007, 27,658 unintentional drug overdose deaths occurred in         the United States.     -   Drug overdose deaths were second only to motor vehicle crash         deaths among leading causes of unintentional injury death in         2007 in the United States.

The increase in drug overdose death rates is largely because of prescription opioid painkillers

-   -   Among deaths attributed to drugs, the most common drug         categories are cocaine, heroin, and a type of prescription drug         called opioid painkillers.     -   “Opioids” are synthetic versions of opium. They have the ability         to reduce pain but can also suppress breathing to a fatal degree         when taken in excess. Examples of opioids are oxycodone         (OxyContin©), hydrocodone (Vicodin©), and methadone.     -   There has been at least a 10-fold increase in the medical use of         opioid painkillers during the last 20 years because of a         movement toward more aggressive management of pain.     -   Because opioids cause euphoria, they have been associated         increasingly with misuse and abuse. Opioids are now widely         available in illicit markets in the United States.

There is a need to perfect a “Smart Pill” to prevent deaths by overdose. The answer to this need rests in the present invention which provides for a unique and proprietary capsule with the capability to “know” when there is a prescribed dosage of a certain constituent in the body and prevent any additional dosage to be released into the body.

Sustained and extended release capsules have been available in the pharmaceutical industries for years but they do not prevent the release of a certain constituent into the body, instead they just prolong the time in which it would be released. This does not solve the problem of overdosing.

The present invention addresses the problem of over-dosing, amongst other problems by providing the Smart Pill System. The smart pill system comprises several technologies (e.g., silicon, sensors, peer wireless communication), different devices (e.g., pill itself, enabling terminals), and an encrypted network for communication and data storage. The system is able to ensure reasonable anti-counterfeit and origin traceback, with a multilayered security system, and good overdose protection. On the top of the present system one can build a full system of diagnoses, follow-up, automatic dosage, and health management.

The smart pill itself is a self-contained electronic device with, e.g., a micro controller, memory, wireless communication capabilities, onboard sensors, and a Micro-Electro-Mechanical System (MEMS) drug delivery system. The devices can communicate with the pill are called programming terminals which are may be linked to a central database using a protected encrypted network. The central database stores, e.g., all the relevant pill information, tracks and enables its uses at all levels from manufacturer to patient, makes possible expiring date tracking and prevents unauthorized use of the pills. The smart pill comprises e.g., a printed flex circuit contain the micro controller with Flash memory, sensors, One Time Programmable memory, wireless communication and antenna, wrapped around drug compartment, e.g., MEMS pump, and battery.

The smart pill has a built in sensor that knows when one or more additional smart pills are in the body and if they are detected, the “API” Active Pharmaceutical Ingredient will not be released. Thru Micro-encapsulation the present invention uses a programmable sensor. The sensor is programmed via RF or other means to tell the sensor in each capsule the prescribed dosage. i.e.: 200 mg in a 4 hour period. Each capsule knows when another capsule is in the body via the sensors contained therein. The Drug Company or the Pharmacist would preset the sensor to know what its prescribed dosage is. The patient would take his prescribed dosage of one or more pills. The sensors detect one another and also detect that they are the only two pills in the body and thus release the API into the system. The release of API can be through a variety of means; osmotic plug piston, polymer cracking or trigger initiated solubolization on the capsule itself or other capsule voids, release from ion-bound linkage from polymer side chains to release the API. Another embodiment of the present invention, one which could be pharmacist controlled is by controlling the release of the active ingredient: release/pump it in the dissolving part of the pill, neutralize/block the active part. The smart Capsule can also be obtained by: sealing the passage to the dissolving part, neutralizing the active part by “cement” it in an inert material and chemically or physically (temperature/light etc) neutralize the active ingredient. Another embodiment of the present invention in a pump form which could be controlled for emergencies could also be described like two electrodes in water. The water compartment has a flexible wall. If you start making the water electrolyze you will obtain gases, which will increase the volume and press outward the flexible wall (or a piston). Thus no motor is required in this embodiment.

If the patient takes an additional quantity of pills (one or more than prescribed dosage) the new pills entering the system will detect the presence of the previous pills that have already released their API load and may also detect the quantity of metbolites. The detection can be made via RF signal, pH, acidity level, detection of drug or metabolites presence, etc. If the detection of released capsules is made by the newly entering capsules, those capsules will not release their API into the system and instead travel through the body as whole units and be released through the anus in the feces. No further API would be released into the system unless the sensor detects that it is the prescribed time of entry, timed drug half-life, sensor detected drug depletion (initial drug and/or metabolites). Batteries if needed can be encapsulated so as to not be a material threat to the patient.

The Smart Pills can also detect other API's, drugs of abuse; alcohol; pregnancy and can prevent release of teratogenic APIs when the patient is determined to be pregnant. The Smart Pills can also use a variety of sensors including but not limited to electronic, biological, chemical, harmonic, and digital sensors.

Smart Pills can be preprogrammed by the manufacturer and/or the pharmacist to prevent drug interactions. i.e.: a drug is taken by the patient and either intentionally or in error another drug which should not be combined with the first drug is taken. The second drug detects the first drug and the API is not released into the system. Smart Pills could also be preprogrammed by the pharmacist to know the patient. The capsules recognize certain features about the patient's physiology and would only release the API into the system of the prescribed user, thus preventing unauthorized usage by others who are not prescribed the drug.

Smart Pills can also be made in pill, tablet, and a variety of other packaging for home or clinical usage, whether through administration by intravenous, oral, rectal, etc. All embodiments are for use with humans as well as animals and have application in agricultural use too.

This invention further relates to an attachable device for retail packaging configured for wireless communication with other retail packages with the devices. In exemplary embodiments, the smart pill system incorporates this technology.

Retail packages are conveniently placed upon retail shelves but they need human interaction to take inventory of the shelves and to stock the shelves. If the human is not diligent the shelf can remain empty and the consumer would not be able to purchase the desired product.

Many high tech endeavors have been applied to this problem including but not limited to wireless devices on the shelves themselves, wireless devices to scan bar codes on the packages and human tallying of the items themselves usually with bar code readers.

All of the above works but tend to be very costly and only the high end retailer can afford to structure the retail environment with the technology. The present invention levels the playing field and makes the technology available to every retail establishment that has access to a “Smart Phone”, a tablet or a computer through the use of an Inventory Application (“APP”) that maintains the data being sent by the wireless devices. The Present Invention consists of a digital tag that is attached or made a part of each package, label, etc. It can incorporate or be made a part of the UPC Bar Code and retains that information as part of its digital signature. The human who maintains the inventory simply walks by the shelves and receives a signal that the package on the shelf transmits. The tags also speak to one another when they arrive on the shelf to determine quantity on the shelf. This information is also wirelessly sent to the APP.

FIG. 9 provides an exemplary wireless communication protocol where more than one Smart Pill is ingested by an individual. This protocol, among other things, prevents inadvertent or intentional overdosing by the individual who ingests them. In general, each ingestible drug delivery device initially “listens” for the broadcast of another ingested drug delivery device. If no signal is received within a predetermined period of time, that ingestible drug delivery device declares itself the “master” and begins to broadcast a signal at periodic intervals. Any subsequently ingested drug delivery devices will receive the broadcast signal and will deactivate their API delivery mechanism while responding with their particular ID number that is stored by the “master” in time sequence. If subsequently ingested drug delivery devices are permitted by the physician, when the master reaches its destination or final dispensement, it communicates to the ingested drug delivery device that entered the individual's body just after the master entered to be the new “master.” In addition, the time sequence by ID number is also transmitted from the old master to the new master. If, on the other hand, only the master was permitted to dispense the API, then no new master is declared and all subsequently-ingested drug delivery devices remain inactive for their duration in the individual's body.

Bronzino, Ed., Copyright 2000, CRC Press LLC, pp. V-1-51-9; Morrison et al., “Clinical Applications of Micro- and Nanoscale Biosensors” in Biomedical Nanostructures. Edited by K. E. Gonsalves, C. L. Laurencin, C. R. Halberstadt, L. S, Nair. 2008, John Wiley & Sons, Inc.; and U.S. Pat. No. 6,802,811, each of which is incorporated herein by reference.

An optical sensor can be configured to measure the optical absorption, optical emission, fluorescence, or phosphorescence, luminescence of an analyte or an associated tag or binding element, other tissues of interest, or combinations thereof. Such optical properties can be inherent optical properties of the analyte, e.g. autofluorescence, or can be optical properties of materials added or introduced into the body of the subject that interact with the analyte, other tissues of interest, or combinations thereof. Optical sensing of materials in blood, for example, is described in Mattley et al., “Blood characterization using UVNIS spectroscopy” Proc. SPIE Advances in Fluorescence Sensing Technology II, Joseph R. Lakowicz; Ed. Vol. 2388, p. 462-470, 1995 and U.S. Pat. Nos. 5,589,932 and 7,027,134, each of which is incorporated herein by reference.

The ingestible drug delivery devices may include one or more sensors configured to sense the blood glucose levels in the subject. The one or more sensors can include a glucose sensor that is either an integral part of the device, wherein the sensors is operably connected to the programmable microprocessor as described herein, or is in a separate device, for example a glucose sensing device in wireless communication with the programmable microprocessor in the device described herein. A number of different glucose monitors have been described using, for example, pin prick, transdermal, or implantable devices. See, e.g., U.S. Pat. Nos. 4,436,094; 4,953,552; 5,497,772; U.S. Patent Applications 2010/0049021; 2010/0081910; each of which is incorporated herein by reference. The one or more sensors can include one or more electrochemical- or photochemical-based sensors wherein a measurable chemical reaction occurs in response to the presence of one or more analyte. For example, many electrochemical sensors use enzymes as specifiers for the analyte. The enzymes cause a chemical reaction, such as a reduction reaction, and electrons released by the reaction are transferred to a mediator molecule, which itself is converted. The mediator then transfers the electrons to an electrode for electrochemical measurement or transfers the electrons to an indicator molecule for photochemical responses. Ferrocene derivatives and hexacyanoferrate are examples of one-electron mediators. Quinones are an example of two-electron mediators. A glucose sensor included in the device uses as the specifier an oxidoreductase that oxidizes glucose to gluconolactone. Electrons from the glucose are then transferred to the oxidized form of a mediator molecule, which in turn delivers the electrons to an electrode. The amount of electric current generated is proportional to the amount of glucose in the sample, and electronics within the sensor convert the signal, and the signal is communicated to the programmable microprocessor or the electronics module that is operably connected to the programmable microprocessor. See, e.g., Hones, et al., Diabetes Techn & Therap, 10: Supplement 1 S10-S26, 2008. Examples of commercially available glucose monitors using such technology in measuring blood glucose levels of a subject include, but are not limited to, OneTouch® blood glucose monitors (LifeScan-Johnson & Johnson, Milpitas, Calif.), Accu-Chek® blood glucose monitors (F. Hoffman-Roche A G, Basel, Switzerland), and Ascencia® blood glucose monitors (Bayer HealthCare LLC, Tarrytown, N.Y.).

The FreeStyle Navigator® glucose monitor, for example, is biocompatible chip implanted into the abdomen or back of the upper arm of a subject and includes an external receiver. Similarly, blood glucose sensor-enabled radio frequency identification (RFID) devices have been described for active monitoring of glucose. See, e.g., Moore, J. Diabetes Sci. Technol. 3: 180-183, 2009, which is incorporated herein by reference.

In an aspect, the one or more sensors can use a charged coupled device (CCD) or complementary metal-oxide-semiconductor (CMOS) sensor, for example, in combination with a binding element that exhibits altered optical properties, e.g., fluorescence, in response to binding an analyte. For example, glycerol and/or free fatty acids can be analyzed using one or more of the sensors. A sensor for measuring a free fatty acid can include an acyl-CoA-binding protein which exhibits an increased fluorescence yield in response to binding a fatty acid. See, e.g., Wadum, et al., Biochem. J., 365: 165-172, 2002, which is incorporated herein by reference.

In an aspect, the one or more sensor can include a binding element, e.g., an antibody or oligonucleotide aptamer, configured to exhibit Forster or fluorescence resonance energy transfer (FRET) in response to binding one or more analytes in the subject. FRET is a distance-dependent interaction between the excited states of two fluorophore molecules in which excitation is transferred from a donor molecule to an acceptor molecule without emission of a photon. For use in a sensor, one or more binding molecules, e.g., antibodies or oligonucleotide aptamers, associated with the one or more sensors are configured with at least one donor molecule and at least one acceptor molecule. The interaction of an analyte with the binding molecule of the sensor results in a conformation change in the binding molecule, leading to changes in the distance between the donor and acceptor molecules and changes in measurable fluorescence.

Donor and acceptor fluorophore pairs can be considered for FRET including, but not limited to, fluorescein and tetramethylrhodamine; IAEDANS and fluorescein; fluorescein and fluorescein; and BODIPY FL and BODIPY FL, and various Alexa Fluor pairings as described herein. The cyanine dyes Cy3, Cy5, Cy5.5 and Cy7, which emit in the red and far red wavelength range (>550 nm) as well as semiconductor quantum dots can also be used for FRET-based detection systems. Quenching dyes can also be used to quench the fluorescence of visible light-excited fluorophores, examples of which include DABCYL, the non-fluorescing diarylrhodamine derivative dyes QSY 7, QSY 9 and QSY 21 (Molecular Probes, Carlsbad, Calif., USA), the non-fluorescing Black Hole Quenchers BHQ0, BHQ1, BHQ2, and BHQ3 (Biosearch Technologies, Inc., Novato, Calif., USA) and Eclipse (Applera Corp., Norwalk, Conn., USA). A variety of donor fluorophore and quencher pairs can be considered for FRET associated with the binding molecule including, but not limited to, fluorescein with DABCYL; EDANS with DABCYL; or fluorescein with QSY 7 and QSY 9. In general, QSY 7 and QSY 9 dyes efficiently quench the fluorescence emission of donor dyes including blue-fluorescent coumarins, green- or orange-fluorescent dyes, and conjugates of the Texas Red and Alexa Fluor 594 dyes. QSY 21 dye efficiently quenches all red-fluorescent dyes. A number of the Alexa Fluor (AF) fluorophores (Molecular Probes-Invitrogen, Carlsbad, Calif., USA) can be paired with quenching molecules as follows: AF 350 with QSY 35 or DABCYL; AF 488 with QSY 35, DABCYL, QSY7 or QSY9; AF 546 with QSY 35, DABCYL, QSY7 or QSY9; AF 555 with QSY7 or QSY9; AF 568 with QSY7, QSY9 or QSY21; AF 594 with QSY21; and AF 647 with QSY 21.

The light-based signal or electrical signal to the sensor is converted by a transducer, e.g., within the digital processing unit, into within the digital processing unit, which then processes the data into information that can be stored, analyzed, and communicated, including, for example, at least one resulting instruction. The electronics module provides the at least one resulting instruction to the programmable microprocessor.

The one or more sensors configured to provide information regarding one or more physiological conditions of the subject can include one or more microcantilevers.

The electronics module provides the at least one resulting instruction to the programmable microprocessor. In some aspects, the one or more microcantilevers can be a nanocantilever with nanoscale components. The one or more microcantilevers and/or nanocantilevers can be arranged into arrays. Both microcantilevers and nanocantilevers can find utility in microelectomechnical systems (MEMS) and/or nanoelectomechnical systems (NEMS).

The one or more sensors for sensing analytes can include a field effect transistor (FET) based biosensor.

The one or more receptors can be ion channels that open and close in response to binding of a specific analyte. The open and closed states can be quantitatively measured as changes in impedance across the lipid bilayer. The changes in impedance measured and transmitted as data by a transducer.

The one or more sensors can include cells with binding molecules that induce a measurable or detectable change in the cells, e.g., a luminescent signal, when bound to analytes. For example, one can use a bioluminescent bioreporter integrated circuit in which binding of an analyte to an engineered cell induces expression of a reporter polypeptide linked to a luminescent response. See, e.g., U.S. Pat. No. 6,673,596; Durick & Negulescu Biosens. Bioelectron. 16: 587-592, 2001, each of which is incorporated herein by reference.

In an aspect, the one or more calorimeter can include an indirect calorimeter configured to assess the physical activity of the subject by periodically monitoring heart rate, body temperature, skin resistance, motion/acceleration sensing, velocity and providing an estimate of caloric intake/energy expenditure. The indirect calorimeter can include one or more of a temperature sensor, a heart rate sensor, an accelerometer, a global positioning system, or a combination thereof. See, e.g., U.S. Patent Application 2009/0240113, which is incorporated herein by reference. An example of a wireless patch system configured for estimating energy expenditure has been described and includes sensors, electrodes, and accelerometers. This system measures a variety of physiological conditions including temperature, heart rate, respiratory rate, and skin conductivity and uses this information in an algorithm to calculate the number of calories consumed, the number of calories burned, and the net yield. See, e.g., U.S. Patent Application 2010/0049004, which is incorporated herein by reference. Other examples of calorie counters based on activity measurements have been described. See, e.g., U.S. Pat. Nos. 4,100,401; 4,159,416; 5,815,954; and 7,334,472, each of which is incorporated herein by reference. Other means for performing calorimetry include, but are not limited to, the Haldane gravimetric method, open-circuit calorimeter with mask, spirographic method, assessment of heat loss and oxygen consumption.

The one or more sensors of the device can be configured to send data regarding a physiological condition in the subject to the programmable microprocessor of the device or to a electronics module operably connected to the programmable microprocessor. Conversely, the electronics module can be configured to instruct the one or more sensors to collect and transmit data or other information regarding one or more physiological conditions or indicators thereof at specified regular intervals and/or when triggered by sensed events or by initiation of particular device activity. The device may further include information storage. For example, measurement of one or more physiological condition may be collected and stored at specified times on a daily basis with an associated time stamp. More than one physiological condition may be measured simultaneously and associated with one another during processing. For example, measurement of temperature, or a localized temperature of an associated nerve tissue or circulatory tissue, can be assessed at the same time as measurement of blood glucose levels. A temperature measurement can also be triggered by other sensor activity such as when a measured exertion level reaches a specified limit value or immediately following caloric intake.

Smart Pill 20 And Associated Encrypted Network 100

As mentioned previously and as shown in FIG. 1, the smart pill 20 itself is a self-contained electronic device comprising onboard sensors 22, bio-active substance modules (e.g., a MEMS drug delivery system) 24, an electronics module 26 and a power source (e.g., battery) 28. The electronics module 26 comprises a microprocessor (e.g., a micro controller) 26A, memory (e.g., flash memory, OTP-one time programmable memory, etc.) 26B, and wireless communication capabilities (e.g., a transponder) 26C having an antenna 26D. By way of example only, the smart pill 20 is implemented on a printed flex circuit 30 (see FIGS. 2A-2B) in which the antenna 26D is embedded therein. This flex circuit 30 is then rolled and formed into a capsule configuration, as shown most clearly in FIG. 2B.

The devices that can communicate with the pill 20 are called programming terminals 27 which are may be linked to a central database 29 (via a wireless interface 29A) using a protected wireless encrypted network 100 (FIG. 1). In particular, the programming terminals 27 are wireless devices that the patient and the healthcare provider (e.g., pharmacist, physician, pill manufacturer) use to communicate with the pill 20. The device 27A is used by the patient and may comprise a smartphone supporting a secure software application for communicating with the pill to verify that the patient about to ingest the pill is the proper patient. The “app” on the device 27A is specifically configured and limited to patient-pill communication; thus, the patient is not enabled to alter the pill software other than to upload proper patient ID thereto. On the other hand, the device 27B is used by the healthcare provider and may also comprise a smartphone supporting a secure software application that provides the authorized healthcare provider with the ability to program the pill 20 to dispense API in accordance with physician prescription for the designated patient. It should be noted that the use of the phrase “patient interface device” or “patient level terminal” or “programming device” are directed to the devices 27, whether it be operated by the patient or by the healthcare provider. It should be further noted that the pill-to-pill communication (e.g., when ingested-see FIG. 9) is also part of this wireless encrypted network 100. The central database 29 stores, e.g., all the relevant pill information, tracks and enables its uses at all levels from manufacturer to patient, makes possible expiring date tracking and prevents unauthorized use of the pills. The smart pill comprises e.g., a printed flex circuit contain the micro controller with Flash memory, sensors, One Time Programmable memory, wireless communication and antenna, wrapped around drug compartment, e.g., MEMS pump, and battery.

An alternative to the pill's API dispensing mechanism may comprise the use of an electrolytic actuator, as shown most clearly in FIGS. 2C-2E. In particular, the pill comprises an electrolytic actuator 40 having an operative end 40A comprising an elastic membrane. In the pill's 20 initial state (FIG. 2C), the membrane 40A is separated from the API by a vacuum 41. When commanded by the microprocessor 26A, the electrolytic actuator 40 causes the elastic membrane to inflate/expand, thereby separating the pill's 20 capsule compartments 20A/20B to permit the dispensing of the API, as shown in FIG. 2D. Furthermore, an alternative to having the pill components 20A/20B separate upon actuator activation, an internal hinge 42 may be provided to keep these components 20A/20B connected while permitting dispensing of the API.

Multilevel Security System

The multilevel security system is implemented at pill level, e.g., as a set of flags than can be raised (enabled) with certain commands and only in sequence (for the first twelve flags). The delivery system of the active ingredient is triggered if and only if the configuration of the flags is the pre-defined one. Moreover the configuration of the flags can be modified only in sequence, one at a time.

The pill security system works, e.g., like a Yale locking system where each security flag F acts like a mechanical pin, preventing the activation (key turn) of the drug delivery system. Moreover, the modification of a security flag is possible only if the previous flags (i.e. the higher activation levels) are correctly configured.

The following flags (implemented as bit level variables are envisaged):

F0: Pill terminated

F1: Pill enabled by the drug manufacturer

F2: Pill enabled by the pharmacists.

F3: Timer for controlling prescription due date started: e.g., a generic 30 days (or 60 days). In the first version could be disabled.

F3B: Pill enabled at user level. It will be used in the future applications, for the moment just reserved.

F4: Pill is ingested [status]. In the simple way is decided if the temperature is over 36° C. for at least ten minutes. For the complex system is a decision based on the readings from different sensors.

F5-F8: Reserved for different triggers connected to various measurements that the pill will be able to perform.

F8-F11: Reserved for counting the pills in case of multiple pill dosage (further developments).

F12: No other pill detected used for one pill dose.

F13-F15: Counter for command authentication errors. It prevents brute force attacks on the pill, disabling it after e predefined number of non authenticated attempts of communications.

Pill Command Security System

The pill security system is e.g., implemented via One Time Programming (OTP) of silicon. In certain embodiments, it may comprise the following components:

PID: The pill has a unique ID (e.g., 16 ANSI alphanumeric characters should be enough) S1: Shared secret: Cryptographic key programmed in the silicon. AS1: authentication system using public challenge P1, expected result R1 and method of computing M1.

The pill, presented with the pairs (P1, R1) uses the method M1 (for example symmetrical key algorithm for a good security, or pre-programmed random lookup table for a simpler one) and the secret seed S1 to compute the result of encryption of P1. If the result matches R1, the pair is a legitimate challenge and can authenticate the execution of one instruction. The authentication errors are used to increase the F13-F15 counter. The initial value of the F13-F15 can be pre-set thus setting the threshold for errors after which the pill considers that the communications attempts are only tempering tentatives. See FIG. 3.

The communication with the pill is not encrypted in order to have faster communication and enable emergency commands (see “Emergency overdose system”).

Pill to Pill Communication

A peer communication system (FIG. 4) using already existing systems will be implemented using a standard like ZigBee. ZigBee is a standard for communications that can be used to build M2M networks using small, low power, low cost battery operated digital radios. It is designed to work in harsh environments and is encrypted using a 128 Bit AES key. The ZigBee natively supports both star and tree networks, and generic Mesh networking. Using tree and mesh networks the coverage and communication distances can be dramatically extended allowing full warehouse coverage. It is a low power alternative to WiFi and Bluetooth connections.

In order to have a lighter and more energetic efficient communication one can use the EnOcean or even MyriaNed. MyriaNed is basically a self-organizing, “gossiping” Wireless Sensor Network. “An arbitrary node will broadcast a new message into the network. In general this will be initiated by a new sensor reading. This message will reach a number of nodes, but not all. Because the nodes also re-sent the received information, the information is spread through the network, and eventually the message is “known” by every node in the network. Epidemic message flooding through the network [is] called gossiping. Every node will have this ‘behaviour’, so at any time, every node is familiar with the state of all other nodes in the network, hence the state of the (distributed) system. This is called a shared state, which reflects the environmental situation that the network is in. So the system is situational aware. Applications of the net as substitute for RFID are also provided.

All of the above technologies offer layer five networking abstraction (net protocol). The smart pill system may comprise, e.g., a simpler layer 5 should be developed, or even use directly layer 4.

Terminal to Pill Communication

The terminal to pill is a point to point communication, thus requiring a much simpler system. The smart pills may comprise, e.g., two systems: a passive point to point, derived from, e.g., NFC/RFID standards, and a more complex Pill to Pill as indicated above which is activated only after ingestion, reducing the level of energy consumption during the pill lifetime. For a future, complex system the extension of the Pill to Pill communication towards the terminal to pill communications is recommendable, but requires more development effort. They are not necessary in the first of pills, but are envisaged for the following ones. All choices of networks presented allow the reading in any moment of the ingested pill unique ID (PID—see below) and thus the possibility to find during an emergency if pills were ingested and their type. (See FIGS. 5-9).

Set of Instructions

In order to make the system safer only a [very] reduced number of commands are allowed:

get PID: returns pill's PID.

enable F1, F2, F3 or F4 (P1,R1): enables the flags and starts the timer. Returns the operation exit code.

get F13-F15 (P1,R1): returns the number stored in F13-F15. In this way one can asses if the pill was subject to tempering or is disabled due to tempering attempts.

During the trial period there will be one more command:

get status (P1,R1): returns the status of all variables in the pill for enabling debug.

Command Authentication System

The “supplier/manufacturer” has a database with all the pills, univocally connecting PID, S1, M1, and all dug related data (type, batch, date, dosage etc.). When requested to supply an authentication challenge-response (P1,R1) it generates a random P1 and computes R1 using M1. It then supplies this pair over the delivery encrypted network that it used to give a command to the pill. The command exit is registered in the database, among with other information like programming terminal ID, patient terminal ID, pill status etc.

Communication/Authentication Network

The network is composed by the main database and programming terminals. The function and encryption is somewhat similar to the same to POS pay card terminals/network and includes:

-   -   terminal authentication (TERM ID)     -   encrypted communication channel     -   terminal physical anti temper

Emergency Overdose System

Furthermore, when the smart pill 20 is ready for delivery (e.g., during an arbitrary defined interval), it is able to receive an emergency kill command which overrides all the security levels. This can happen only to a smart pill 20 that has passed the overdoes protection system. As a result, the flag F0 changes to disable.

Alternative Protocol for Avoiding Inadvertent and Intentional Overdosing

As mentioned previously, FIG. 9 provides smart pill 20 (also referred to as “capsule”) communication that designates the earliest ingested smart pill 20 as a “master” whose API is dispensed properly and all subsequently ingested smart pills 20 are identified in the time sequence of ingestion. With one smart pill 20 identified as the “master,” all of the subsequent smart pills 20 are prevented from dispensing any further API, thereby preventing inadvertent as well as intentional overdosing. If the proper passage of time occurs following the proper dispensing of API from the “master” smart pill 20, the next-in-time ingested smart pill 20 becomes the “master” and is provided with the time sequence of ingestion data of subsequent smart pills 20 from the previous outgoing master smart pill 20.

It should be further understood that the identity of the healthcare provider that prepares/programs the smart pill (viz., see first two blocks in FIG. 9) must be included in the smart pill's 20 internal stored data, as well as any serial number from the smart pill manufacturer. This aspect of the smart pill configuration thus prevents counterfeiting since the smart pill's 20 source identity and preparer identity are memorialized within the smart pill 20 memory from its inception. Futhermore, this identity data cannot be manipulated or changed without the proper authorization. This is one of the purposes of the OTP memory, discussed previously, namely, to store initial critical pill data (e.g., source data including pill serial number, etc.) that cannot be erased, re-programmed, tampered with and/or modified, thereby preserving the provenance of the pill and preventing any counterfeiting of it.

Smart Pill Drug Delivery System

The smart pill drug delivery system may comprise an electroytical pump, as used in opthalmological procedures. As shown most clearly in FIGS. 10A-10C, the pump displaces liquid by creating pressure through a volume increase due to gas creation through electrolysis of water. If required, the pressure system pushes a “piston” that effectively empties the pill's active ingredient compartment. The flow through a minute pipe is further controlled by a valve that, when closed, also blocks access of foreign liquid inside the smart pill 20. Furthermore, this drug delivery system can be used to dose the quantity of drug released or even establish a “neutralizer” release system by means of a secondary delivery system in the smart pill 20. An alternative embodiment may comprise a micro-mechanical actuator that slides a “cover” over the active ingredient.

Treatment

The ingestible drug delivery device can be used in a method for treating a disorder in a vertebrate subject. The method can include releasing at least one bioactive substance to one or more tissues of the vertebrate subject with one or more bioactive substance module and/or deactivation modules, wherein the one or more bioactive substance module and/or deactivation modules are configured to release substance, and controlling the one or more bioactive substance module and/or deactivation modules with a programmable microprocessor configured to provide instructions to the one or more bioactive substance module and/or deactivation modules in response to information regarding one or more physiological conditions of the vertebrate subject. The method can further include providing one or more medicaments in combination with applying the device configured to release bioactive substance for the treatment of a disorder.

The method for treating a disorder in a subject can further include providing the ingestible drug delivery device as described herein comprising one or more medicaments configured to treat a disorder. The medicaments can include one or more medicaments for the treatment of veterinary and human conditions.

The method for treating a disorder in a subject can further include providing the ingestible drug delivery device as described herein wherein the one or more sensors may be configured to provide data to the electronics module and/or the programmable microprocessor regarding the plasma, blood, and/or tissue levels of bioactive substance. The programmable microprocessor may be configured to respond to the data received from the sensors by adjusting the one or more bioactive substance module and/or deactivation modules to appropriately release and/or not release the bioactive substance and/or deactivation substance in order to titrate, for example, blood and/or or plasma concentration, to for example, treat a condition or prevent overdose. Alternatively or in addition, the electronics module is configured to process the data from the sensor and provide instructions and/or programming to the programmable microprocessor to adjust the one or more bioactive substance module and/or deactivation modules to appropriately release the deactivation substance to, for example, deactivate the bioactive substance.

The method for treating a disorder in a subject can further include providing the ingestible drug delivery device as described herein wherein the ingestible drug delivery device may be configured to have a “controlled” quantity, e.g., a partial bioactive substance delivery in the instance where a full load of bioactive substance would go over, for example, a “threshold cutoff” blood, plasma, and/or tissue concentration of the bioactive substance but is not high enough to provide the correct dosage until the next dosing time point.

The method for treating a disorder in a subject can further include providing the ingestible drug delivery device as described herein wherein the ingestible drug delivery device may be configured to monitor the dosage prescribed by the health care provider for the diagnosed condition and it's effectivity with treating the particular symptom. For example, establishing two cutoff levels for pain sensing/alleviation and if the dosing is insufficient for the management for the amount of pain this information could be communicated back to the health care provider for an adjustment in the dosage and/or a change in the medicament selected.

Glucocorticoid Receptor Antagonists

Glucocorticoid receptor antagonists bind to the receptor and prevent glucocorticoid receptor agonists from binding and eliciting GR mediated events, including transcription. RU486 is an example of a non-selective glucocorticoid receptor antagonist.

Compounds having high glucocorticoid receptor binding affinity and, in addition, high in vivo anti-glucocorticoid activity, while having, for example, low androgenic and progestagenic activities are disclosed in U.S. Pat. No. 6,011,025, incorporated herein by reference in its entirety. ORG 34517 is an example of a compound with high glucocorticoid receptor binding affinity while having low androgenic and progestagenic activities. Therapeutic compositions and methods using ORG 34517 are disclosed in U.S. Pat. No. 8,986,677, incorporated herein by reference in its entirety.

It has been found that 11-(substituted phenyl)-estra-4,9-diene derivatives of formula I

wherein

A is a residue of a 5- or 6-membered ring containing 2 heteroatoms which are not connected to each other and independently selected from O and S, the ring being optionally substituted with one or more halogen atoms, or A is a residue of a 5- or 6-membered ring wherein no double C—C bonds are present, containing 1 heteroatom selected from O and S, which heteroatom is connected to the phenyl group at the position indicated with an asterisk, the ring being optionally substituted with one or more halogen atoms; R1 is H or 1-oxo(1-4C)alkyl; R2 is H, (1-8C)alkyl, halogen or CF3; X is selected from (H,OH), O, and NOH; and the interrupted line represents an optional bond, show specific and high glucocorticoid receptor binding affinity and are highly active in vivo showing predominant anti-glucocorticoid activity.

The compounds lack appreciable affinity for mineralocorticoid, progesterone, estrogen and androgen receptors, indicating a clean side effect profile.

The 11-(substituted phenyl)-estra-4,9-diene derivatives of the invention can be used in the prevention and treatment of glucocorticoid dependent diseases or symptoms, like Cushing syndrome, diabetes, glaucoma, sleep disturbances, depression, anxiety, atherosclerosis, hypertension, adiposity, osteoporosis and withdrawal symptoms from narcotics and their mixtures.

Preferred compounds according to this invention are 11-(substituted phenyl) estra-4,9-diene derivatives, wherein the heteroatom(s) are (is) O, the 5- or 6-membered ring being optionally substituted with one or more fluorine atoms; R1 is H; and X is O or NOH.

More preferred compounds are 11-(substituted phenyl) estra-4,9-diene derivatives wherein A is a residue of a 5-membered ring. Particularly preferred are 11-(substituted phenyl) estra-4,9-diene derivatives wherein A contains 2 heteroatoms being O.

Especially preferred are 11-(substituted phenyl) estra-4,9-diene derivatives wherein R2 is methyl and the interrupted line represents a bond.

The most preferred compound is (11β,17β)-11-(1,3-benzodioxol-5-yl)-17-hydroxy-17-(1-propynyl) estra-4,9-dien-3-one (ORG 34517).

The term halogen means a fluorine, chlorine, bromine or iodine atom. Fluorine is the preferred halogen in ring A and when R2 is halogen, chlorine is preferred.

The terms (1-4C)alkyl and (1-8C)alkyl, as used in the definitions of R1 and R2, respectively, mean alkyl groups having 1-4 and 1-8 carbon atoms, respectively, for example methyl, ethyl, propyl, isopropyl, butyl, sec-butyl, tert-butyl, pentyl, neopentyl, hexyl, octyl.

The 11-(substituted phenyl)-estra-4,9-diene derivatives according to the present invention can be prepared by a process wherein a compound of formula II

wherein A, R2 and the interrupted line have the meanings as previously defined, R1 is H, and P is a protected keto-group, is dehydrated and deprotected, after which the 17β-OH is optionally esterified by reaction with an appropriate carboxylic acid to give a derivative wherein R1 is 1-oxo(1-4C)alkyl, and optionally the 3-oxo group is converted into the corresponding 3-hydroxy- or 3-oxime derivative. The 3-oxo group can be reduced to form the 3-hydroxy-derivative by using a suitable reducing agent, such as sodium borohydride. The 3-oxime derivatives can be prepared by hydroxylamine treatment in a suitable solvent, like pyridine.

The derivatives of formula II may be prepared according to well known methods described and used for the preparation of steroids.

A suitable process for the preparation of derivatives of formula II starts from estra-4,9-diene-3,17-dione. Selective reduction of the 17-keto group to 17β-OH, 17α-H, e.g. with sodium borohydride, followed by protection of the 3-keto group, e.g., by ketalisation with ethyleneglycol, triethylorthoformate and p-toluenesulfonic acid, and oxidation of the 17-hydroxy group, e.g. with pyridinium chlorochromate, provides the 3-ketoprotected estra-5(10),9(11)-diene-3,17-dione. Alkynylation at the 17-position (yielding a 17α-alkynyl,17β-OH derivative), followed by epoxidation of the 5(10) double bond, e.g. with hydrogen peroxide, trifluoroacetophenone, and pyridine in dichloromethane according to the method as disclosed in European patent application EP 0 298 020, provides the 3-ketoprotected 5α,10α-epoxy-17α-alkynyl-17β-hydroxy-estr-9(11)-ene-3-one.

Subsequently, compounds of formula II are formed from this epoxide derivative, for example by reaction with an organometallic compound of the formula

wherein X is a (alkali)metal, like lithium, or a magnesiumhalide, preferably magnesium bromide.

Suitable protective groups and methods to remove these groups are known in the art, for example from T. W. Green: Protective Groups in Organic Synthesis (Wiley, NY, 1981). Particularly suitable protective groups for the protection of keto groups are acetals, e.g. 1,2-ethylene ketal.

The specificity of ORG 34517 for GR blockade, without significant cross-binding to other related steroidal hormone receptors (such as those for estrogen and progesterone), eliminates the likelihood of significant toxicities and side effects. Indeed, none were identified in all the substantial phase I and phase II clinical trials that already have been performed with the compound. Because the drug is envisioned as being used in limited dosing over time, coordinated with the intermittent dosing strategies typical for chemotherapeutic agents, the GR blockade also would not lead to significant alteration of HPA-axis functioning, with rapid restitution of the HPA-axis to baseline following dosing.

Combination Therapy

Compositions and methods for treating GC-responsive conditions, including for example, the prevention or addiction induced anxiety and withdrawal side effects as a therapeutic, for wound healing and transplants, for the prevention or treatment of stress induced osteoporosis and for the rapid healing of bone related injuries, and regenerative therapy, in a subject are provided by the present invention.

Methods of treating a GC-responsive condition in a subject are provided according to embodiments of the present invention which includes administering, the ingestible drug delivery device of the invention comprising, e.g., in combination, a GR antagonist and at least one additional therapeutic agent as set forth herein. The phrase “administering in combination” as used herein refers to any form of administration of one or more GR antagonists and at least one additional therapeutic agent as set forth herein.

Addiction and Withdrawal

The present invention relates to methods of and compositions for treating and relieving symptoms associated with substance abuse and withdrawal. The present invention relates to methods of and compositions for treating addiction to, for example, alcohol, drugs, caffeine, sugar, food, nicotine, opiates, and/or marijuana, etc.

Treatment of addiction to prescription medications (e.g., narcotics such as oxycodone, oxycontin, Vicodin), particularly when their use is initiated for the treatment of acute or chronic pain syndromes, can be difficult. Not only is there significant withdrawal following chronic use, but the risk of relapse is significantly increased by the clinical need for continued use.

Substance addiction and abuse is a multi-factorial neurological disease. Over time, repeated exposure to various substances, both endogenous and exogenous, causes modification of the neurotransmission circuits and adaptations in post-receptor signaling cascades. There are several effects of this neuronal modification. Among them, there is a reduction in the ability of natural rewards to activate the reward pathways leading to depressed motivation and mood and an increased compulsion to compensate for the physiological change.

While the common perception underlying addiction is that of a “reward circuit”, pleasure may not necessarily be a strong enough impetus to drive people towards their addictions. Rather, addictive behavior arises from an intense desire to manage and/or avoid the anxiety that arises when someone is experiencing withdrawal.

Traditional treatments for substance dependency, such as benzodiazepine abuse, have been based upon cognitive-behavioral therapy or drug therapy, or a combination thereof. Conventional methods of treatment fail, however, in that they do not address the physiochemical changes that occur with addiction and dependence. Thus, conventional treatments for controlling withdrawal symptoms and cravings for addictive substances have had limited success and often have undesirable side effects.

What is therefore needed are improved methods of, and compositions and/or devices for preventing addiction to, and physiological dependence upon addictive substances. What is also needed is an improved treatment methodology for controlling cravings and withdrawal symptoms caused by substance abuse.

Accordingly, the invention provides methods of, and compositions and/or ingestible devices for, preventing addiction to, and physiological dependence upon addictive substances. Also provided are methods of and compositions for an improved treatment methodology for controlling cravings and withdrawal symptoms caused by substance abuse.

The present invention relates to the use of, for example, ingestible drug delivery device of the invention comprising, e.g., cortisol blockers (glucocorticoid receptor [GR] antagonists) for the prevention or addiction induced anxiety and withdrawal side effects as a therapeutic and in concert with a diagnostic.

The ingestible drug delivery device of the invention may be administered orally. The ingestible drug delivery device of the invention may comprise, e.g. an active pharmaceutical ingredient in combination with pharmaceutically suitable auxiliaries, e.g. as described in the standard reference, Gennaro et al., Remington's Pharmaceutical Sciences. By means of pharmaceutically suitable liquids the compounds can also be applied in the form of a solution, suspension, emulsion, e.g. for use in an the ingestible drug delivery device of the invention.

Suitable carriers with which the compositions can be administered include lactose, starch, cellulose derivatives and the like, or mixtures thereof, used in suitable amounts.

The present invention reflects the role of endogenous glucocorticoids (GCs) in withdrawal from substances of abuse and addictive substances (hereafter referred to as “drug” or “drugs”, inclusive of, but not restricted to, alcohol, nicotine, caffeine, cocaine (including crack cocaine), cannabis, amphetamines (including crystal methamphetamine), opiates and opiate analogues (including heroine, oxycodone, hydrocodone, hydromorphone, methadone), dextromethorphan, benzodiazepines, ecstacy (MDMA), GHB, barbiturates, khat, kratom, PCP, LSD, ketamine, peyote, mescaline, psilocybin, rohypnol, Salvia divinorum, antidepressants, anti-anxiety 5 medications, sleep aids, allergy medications.

Combination treatments of withdrawal from narcotics and subsequent prevention of relapse of, e.g., narcotic use can be accomplished by:

1. treatment with ORG34517 prior to, or at time of withdrawal of narcotic, preventing symptoms of withdrawal (as i think is listed in our original patent for nicotine/alcohol); followed by:

2. restoration of narcotic use using “smart pill” encapsulation of prescription narcotic, to establish:

-   -   a. new baseline dose for treatment of pain syndromes     -   b. prevent self medication with higher doses     -   c. prevention of overdose     -   d. tracking of narcotics in case of loss/theft/illegal transfer         using “smart pill” encoding of intended patient, intended dose,         and loading pharmacist and pharmacy.

Increased circulating levels of GCs may relate to direct elevating effects of substances of abuse or from stress-associated GC elevations in response to neuropsychiatric and physical stresses of withdrawal.

The present invention relates to using the ingestible drug delivery device of the invention in a method of co-administration of a selective GC receptor antagonist, such as ORG34517 administered during the active intoxication phase of drug use, prior to drug use, or after cessation of drug use to reduce neuropsychiatric and physical symptoms of withdrawal, such as anxiety, hallucinations, dysphoria, depression, delirium tremens, chills, shakes, tremors, akathisia, restlessness, restless leg syndrome, musculoskeletal aches and pains, cramping, chills, weakness, using the ingestible drug delivery device of the invention.

The present invention relates to single dose of GC receptor antagonist or sustained administration of GC receptor antagonist for hours, days, weeks, or months for prevention of and/or treatment of symptoms of drug withdrawal using the ingestible drug delivery device of the invention.

The ingestible drug delivery device of the invention may be designed for co-administration with anti-anxiety drugs and anti-depressant drugs to better control sporadic episodes, flare-ups of anxiety or depression. The invention provides regular co-administration of the ingestible drug delivery device of the invention with anti-anxiety and/or anti-depressant drugs using the ingestible drug delivery device of the invention.

The present invention may also be used in concert with a diagnostic (for example, a diagnostic test using saliva, blood, plasma, serum, urine or tears as substrate) for the specific constituent i.e.: alcohol, cocaine, caffeine, nicotine, etc. to monitor the specific level of said constituent in the individual to prevent from occurrences of anxiety and withdrawals.

The present invention may also be used in concert with a diagnostic (for example, a diagnostic test using saliva, blood, plasma, serum, urine or tears as substrate) for cortisol to determine which individuals have elevated circulating cortisol or dysregulated cortisol and may therefore be most likely to benefit from administration of GC receptor antagonist.

The present invention may be packaged for use alone, as a single dose (by prescription or over the counter), as a limited number of timed doses in packaging designed to specifically guide self-administration, and in combination with drug or cortisol diagnostic test (using saliva, blood, plasma, serum, urine or tears as substrate) for self-administration or administration by health care professional or technician.

Bioactive Substances

The ingestible drug delivery device of the invention may comprise one or more bioactive substances. The bioactive substance may include active compounds, and compounds for veterinary and human use, such as but not limited to: pharmaceutical actives, nutriceuticals, cosmeceuticals, cosmetics, complementary medicines, natural products, foods, vitamins, nutrients, biologics, amino acids, proteins, peptides, nucleotides, and nucleic acids. In a preferred form the bioactive substance is adapted for oral administration.

In a preferred embodiment of the invention, the bioactive substance is an organic compound. In a highly preferred embodiment of the invention, the bioactive substance is an organic, therapeutically active compound for human use. In another embodiment of the present invention, the bioactive substance is an inorganic compound. When the biological active material is a drug, it can be of a neutral species, basic or acidic as well as salts of an acid or base. This invention is not limited to any drug specific class, application type, chemical type or function grouping.

Dosage forms can be administered to the patient on a regimen of, for example, one, two, three, four, five, six, or other doses per day

In order to more finely regulate the dosage schedule, the active substances may be administered separately in individual dosage units at the same time or carefully coordinated times. Since blood levels are built up and maintained by a regulated schedule of administration, the same result is achieved by the simultaneous presence of the two substances. The respective substances can be individually formulated in separate unit dosage forms in a manner similar to that described above.

In formulating the compositions, the active substances, in the amounts described above, may be compounded according to accepted pharmaceutical practice with a physiologically acceptable vehicle, carrier, excipient, binder, preservative, stabilizer, flavor, etc., in the particular type of unit dosage form.

Illustrative of the adjuvants which may be incorporated in the bioactive substance composition are the following: a binder such as gum tragacanth, acacia, corn starch or gelatin; an excipient such as dicalcium phosphate or cellulose; a disintegrating agent such as corn starch, potato starch, alginic acid or the like; a lubricant such as stearic acid or magnesium stearate; a sweetening agent such as sucrose, aspartame, lactose or saccharin; a flavoring agent such as orange, peppermint, oil of wintergreen or cherry. When the dosage unit form is a capsule, it may contain in addition to materials of the above type a liquid carrier such as a fatty oil. Various other materials may be present as coatings or to otherwise modify the physical form of the dosage unit. For instance, tablets or capsules may be coated with shellac, sugar or both. A syrup of elixir may contain the active compound, water, alcohol or the like as the carrier, glycerol as solubilizer, sucrose as sweetening agent, methyl and propyl parabens as preservatives, a dye and a flavoring such as cherry or orange.

Alternatively, the implanted device can include a self-contained power source made using any means of generation or storage of energy, e.g., a primary battery, a replenishable or rechargeable battery, a thin film battery, a capacitor, or a supercapacitor. A replenishable or rechargeable self-contained power source can be replenished or recharged using a radio-frequency link, an optical link, or other energy-coupling link. See, e.g., U.S. Patent Application No. 2005/0143787, by B. Boveja, which is incorporated herein by reference. In an aspect, the power source for an implantable device is supplied from an external power source via a transcutaneous inductive coupling. See, e.g., U.S. Patent Application 2010/0076524, which is incorporated herein by reference.

The power source can include electrical energy generated by mechanical energy of a subject's movement. For example, the power source can be a linear motion electric power generator that uses a rare earth magnet and a coil positioned to move linearly back and forth relative to one another. The movement of the coil in the field of the magnet generates a current in the coil. See, e.g., U.S. Pat. No. 5,347,186, which is incorporated herein by reference. In this instance, power can be generated as the device moves, e.g., bounces up and down while jogging or while doing other physical activity, as exemplified by the nPower® PEG (Personal Energy Generator, from Tremont Electric, Tremont, Ohio). In an aspect, the power source can be one or more solar panel attached to one or more component of the device such as, for example, a portable refrigeration unit in a backpack with affixed solar panels. See, e.g., U.S. Patent Application 2009/0015022 which is incorporated herein by reference.

In an aspect, the power source can include a rubber film configured to harness energy associated with natural body movements. For example, the power source can include a material made of a ceramic piezoelectric material, e.g., fabricated lead zirconate titanate that is embedded in silicone rubber sheets. The rubber film can harness natural body movements such as walking and breathing as electricity when flexed, converting approximately 80% of mechanical energy into electrical energy. See, e.g., Qi, et al., Nano Lett., 10: 524-528, 2010, which is incorporated herein by reference.

The power source can include one or more of a battery or microbattery, a fuel cell or biofuel cell, or a nuclear battery. One or more power sources of the same or different types can be included in the device, without limitation. Batteries for a small implantable device can include a microbattery, e.g., as available from Quallion LLC, Sylmar, Calif. (http://www.quallion.com), or one designed as a film (U.S. Pat. Nos. 5,338,625 and 5,705,293), each of which is incorporated herein by reference. Alternatively, the power source could be one or more fuel cell, for example, a biofuel cell, such as an enzymatic, microbial, or photosynthetic fuel cell (US2003/0152823A1; WO03/106966A2; or Chen T et al.,” J. Am. Chem. Soc. 2001, 123: 8630-8631, each of which is incorporated herein by reference). The fuel cell can be of any size, including the micro- or nano-scale. In an aspect, the power source can include laterally packaged piezoelectric fine wires that convert biomechanical energy (e.g., stretching muscles, beating heart, walking) into electrical energy using a nanogenerator. See, e.g., Yang et al., Nature Nanotechnol., 4: 34-39, 2009; Yang et al., Nano Lett., 9: 1201-1205, 2009, each of which is incorporated herein by reference. In another aspect, the power source can include a pressure-rectifying mechanism that utilizes pulsatile changes in blood pressure or an acceleration-rectifying mechanism as used in self-winding watches, or other types of flow-rectifying mechanism capable of deriving energy from other flow parameters. In an embodiment, the power source can be a nuclear battery. See, e.g., Wacharasindhut et al., Appl. Phys. Lett. 2009, 95: 014103, which is incorporated herein by reference.

In an aspect, the power source can be a power receiver capable of receiving power from an acoustic source or electromagnetic source (e.g., infrared energy, or inductively coupled, as described in U.S. Pat. Nos. 6,170,485, and 7,212,110; U.S. Patent Application No. 2005/0228259; and Budgett et al., J. Appl. Physiol. 2007, 102: 1658-1663, each of which is incorporated herein by reference). The power source can include power generated from thermoelectric heating based on the differential between body temperature of a subject and the ambient temperature. See, e.g., U.S. Pat. No. 6,075,199; U.S. Patent Application 2009/0056328, each of which is incorporated herein by reference. In an aspect, the device can include a power transmitter capable of transmitting power (e.g., acoustic power, electrical power, or optical power) from the device to a secondary location. The secondary location can be, for example, one or more bioactive substance module and/or deactivation modules, one or more sensors, another device, or combinations thereof.

Bioactive Substance Module

The release of the bioactive substance can be through a variety of means; osmotic plug piston, polymer cracking or trigger initiated solubilization on the capsule itself or other capsule voids, release from ion-bound linkage from polymer side chains to release the API. Another embodiment of the present invention, one which could be pharmacist controlled is by controlling the release of the active ingredient: release/pump it in the dissolving part of the pill, neutralize/block the active part. The Smart Pill can also be obtained by: sealing the passage to the dissolving part, neutralizing the active part by “cement” it in an inert material and chemically or physically (temperature/light, etc.) neutralize the active ingredient. Another embodiment of the present invention in a pump form which could be controlled for emergencies could also be described like two electrodes in water. The water compartment has a flexible wall. If you start making the water electrolyze you will obtain gases, which will increase the volume and press outward the flexible wall (or a piston). Thus no motor is required in this embodiment.

Deactivation Module

The ingestible drug delivery device of the invention may comprise a deactivation module. In exemplary embodiments, the deactivation module may comprise one or more deactivation agents which may be, for example, a chemical, and enzyme, and/or a pharmaceutical which can serve to deactivate the bioactive substance. In exemplary embodiments the deactivation module may release its contents into the bioactive substance module to deactivate the at least one bioactive substance. In alternative embodiments, the deactivation module may release its content directly into the patient. In certain embodiments the deactivation module may release a substance, such as a pharmaceutical, which is antagonistic to the bioactive substance. In exemplary embodiments, the deactivation module may comprise, for example, an enzyme, a chemical, and/or a pharmaceutical which can serve to deactivate and/or degrade the bioactive substance to prevent the pollution of the environment by inactivating the bioactive substance before excretion to prevent contamination of waste and wastewater effluents before they reach the environment.

Electronics Module

The electronics module may comprise a processor, a transponder and a memory, said memory comprising data selected from the group consisting of:

(a) data related to a person who is permitted to ingest said ingestible drug medical device;

(b) data related to said bioactive substance;

(c) data related to a healthcare provider that enabled said electronics module;

(d) data related to said sensor;

(e) data related to the provenance of said ingested drug medical device;

Tracking and Delivery Confirmation of Pharmaceutical Products

A system and method are disclosed that track an ingestible drug delivery deliverable to a user. The system includes an identifier or tag secured to the deliverable, a computer system for interrogating the identifier, and a personal device in communication with the computer system, wherein the personal device is held by the user at the time the user is administered the deliverable to detect the unique identity associated with the identifier device and confirms delivery of the deliverable to the user. The method includes attaching an identifiable tag that produces a unique signature to the deliverable, interrogating the tag at about the time of delivery to the user, and confirming that the user has been administered the deliverable through detecting the identifiable tag. The system provides that the ingestible drug delivery device of the invention can communicate with each other and/or with a personal device and/or a computer sustem.

A system and method are disclosed that track a packaged product to a user. The system includes an identifier or tag secured to the deliverable, a computer system or APP for interrogating the identifier, and a personal device in communication with the computer system, wherein the personal device is held by the user at the time the user is administered the deliverable to detect the unique identity associated with the identifier device and confirms delivery of the deliverable, e.g., the ingestible drug delivery device of the invention, to the user. The method includes attaching an identifiable tag that produces a unique signature to the deliverable, interrogating the tag at about the time of delivery to the user, and confirming that the user has been administered the deliverable through detecting the identifiable tag.

Retail Tracking System

Another example of the Invention would be a retail tracking system, which incorporates a digital tag, which may be an attachable device for retail packaging configured for wireless communication with other retail packages with, for example, the devices of the invention. In exemplary embodiments, the smart pill system incorporates this technology. In an exemplary embodiment, the manufacturer of the goods applies the tag as part of or attached to the retail package. The package recognizes and communicates with other packages that are then placed into a shipping box. The box receives a corresponding tag label that tells the in other contents where they will be shipped and by what shipper. This prevents the theft or interception of the contents and maintains a digital signature of the manufacturer, the shipper and the retail establishment that was programmed to receive the goods. If found in the hands of someone who was not the targeted recipient, it can be evidence of the theft.

In an exemplary embodiment, when the box is scanned by the shipper the shipper knows the necessary information for shipping too. Each package knows its size, weight, dimensions, etc., and by communicating with the other packages in the box can also communicate its total contents. The first package that enters the box acts as the master and then retains all information from each subsequent entry to the box as they reach out and communicate with each other.

The box is delivered to the recipient, e.g., a retail establishment. The corresponding APP on the users system (smart phone, tablet, PC, etc.) receives it's communication from the packages that they have arrived. The user then places the desired quantity onto the retail shelves. The packages recognize the quantity placed on the shelf and that they are together. The packages then acknowledge and are aware when each package leaves the shelf as they provide a good bye hand shake to the other packages. All of this communication can be registered and monitored by the User. The last package to leave the shelf communicates with the User that everyone (all the packages) have left the shelf and more are needed from the supply room. The last package will know if the full quantity that was shipped in its box have been depleted or if additional packages are still there ready to be placed on the shelf. When scanned by the cashier the system automatically notifies the APP that the package has left the building and if it is the last one, it also notifies the User that reorders are necessary. It can ask the User if it wants a reorder placed and this can automatically be sent to the manufacturer to expedite the reorder and shipping and replenishment sequence. The system can also be set to varied needs ie: if quantity of packages is down to 6 units . . . re-order. The system is seamless and minimal cost to the retail establishment as it only requires the APP, everything else is provided by the participants of the system. i.e.: the manufacturer of the goods, the shipper, etc.

The Invention makes the package to package communication the key to the entire retail chain of events. It provides a very low cost digital tag which is a part of the retail package when shipped by the manufacturer. It provides continuous communication throughout the packages life cycle and provides a digital signature for every aspect from manufacturer, to shipper, to retailer. It is seamless and can advise the retailer of its life expectance i.e., near expiration date. It can also be tied into a home user APP that provides the consumer with helpful information including but not limited to: recipes, product uses, interaction concerns i.e., never use bleach with ammonia, etc.

In an exemplary embodiment, The digital tag may be attached to the packaging of the ingestible drug delivery devices of the invention. In another exemplary embodiment, the digital tag may be attached to the shipping boxes containing the ingestible drug delivery devices of the invention. In yet another exemplary embodiment, the digital tag may be incorporated into the ingestible drug delivery device itself.

Packaging/Treatment Kits

The present invention relates to a kit for conveniently and effectively carrying out the methods in accordance with the present invention. Such kits may be suited for the delivery of solid oral forms such as tablets or capsules. Such a kit may include a number of unit dosages. Such kits can include a means for containing the dosages oriented in the order of their intended use. An example of a means for containing the dosages in the order of their intended uses is a card. An example of such a kit is a “blister pack”. Blister packs are well known in the packaging industry and are widely used for packaging pharmaceutical unit dosage forms. If desired, the blister can be in the form of a childproof blister, i.e., a blister that is difficult for a child to open, yet can be readily opened by an adult. If desired, a memory aid can be provided, for example in the form of numbers, letters, or other markings or with a calendar feature and/or calendar insert, designating the days and the sections of a day in the treatment schedule in which the dosages can be administered, such as an AM dose is packaged with a “mid day” and a PM dose.; or an AM dose is packaged with a PM dose. Alternatively, placebo dosages, or vitamin or dietary supplements, either in a form similar to or distinct from the pharmaceutical active dosages, can be included.

In one aspect, the package, kit or container comprises a “blister package” (also called a blister pack, or bubble pack). In one aspect, the blister package consists two or more separate compartments: Am dosage of this invention, and PM dosage of this invention, or mid-day dosage of this invention. This blister package is made up of two separate material elements: a transparent plastic cavity shaped to the product and its blister board backing. These two elements are then joined together with a heat sealing process which allows the product to be hung or displayed. Exemplary types of “blister packages” include: Face seal blister packages, gang run blister packages, mock blister packages, interactive blister packages, slide blister packages.

Blister packs, clamshells or trays are forms of packaging used for goods; thus, the invention provides for blister packs, clamshells or trays comprising a composition (e.g., a (the multi-ingredient combination of drugs of the invention) combination of active ingredients) of the invention. Blister packs, clamshells or trays can be designed to be non-reclosable, so consumers can tell if a package has already opened. They are used to package for sale goods where product tampering is a consideration, such as the pharmaceuticals of the invention. In one aspect, a blister pack of the invention comprises a moulded PVC base, with raised areas (the “blisters”) to contain the tablets, pills, etc. comprising the combinations of the invention, covered by a foil laminate. Tablets, pills, etc. are removed from the pack either by peeling the foil back or by pushing the blister to force the tablet to break the foil. In one aspect, a specialized form of a blister pack is a strip pack.

In one aspect, a blister pack also comprises a method of packaging where the compositions comprising combinations of ingredients of the invention are contained in-between a card and a clear PVC. The PVC can be transparent so the item (pill, tablet, geltab, etc.) can be seen and examined easily; and in one aspect, can be vacuum-formed around a mould so it can contain the item snugly and have room to be opened upon purchase. In one aspect, the card is brightly colored and designed depending on the item (pill, tablet, geltab, etc.) inside, and the PVC is affixed to the card using pre-formed tabs where the adhesive is placed. The adhesive can be strong enough so that the pack may hang on a peg, but weak enough so that this way one can tear open the join and access the item. Sometimes with large items or multiple enclosed pills, tablets, geltabs, etc., the card has a perforated window for access. In one aspect, more secure blister packs, e.g., for items such as pills, tablets, geltabs, etc. of the invention are used, and they can comprise of two vacuum-formed PVC sheets meshed together at the edges, with the informative card inside.

In one aspect, blister packaging comprises at least two components (e.g., is a multi-ingredient combination of drugs of the invention): a thermoformed “blister” which houses the product (e.g., a pharmaceutical combination of the invention), and then a “blister card” that is a printed card with an adhesive coating on the front surface. During the assembly process, the blister component, which is most commonly made out of PVC, is attached to the blister card using a blister machine. This machine introduces heat to the flange area of the blister which activates the glue on the card in that specific area and ultimately secures the PVG blister to the printed blister card. The thermoformed PVG blister and the printed blister card can be as small or large. Conventional blister packs can also be sealed (e.g., using an AERGO 8 DUO®, SCA Consumer Packaging, Inc., DeKalb, Ill.) using regular heat seal tooling. This alternative aspect, using heat seal tooling, can seal common types of thermoformed packaging.

As discussed herein, the products of manufacture of the invention can comprise the packaging of the ingestible drug delivery devices of the invention, alone or in combination, as “blister packages” or as a plurality of packets, including as lidded blister packages, lidded blister or blister card or packets, or a shrink wrap.

Other means for containing said ingestible drug delivery devices can include bottles and vials, wherein the bottle or vial comprises a memory aid, such as a printed label for administering said unit dosage or dosages. The label can also contain removable reminder stickers for placement on a calendar or dayminder to further help the patient to remember when to take a dosage or when a dosage has been taken.

Another drug delivery system comprises one or more ball semiconductor aggregations and facilitating release of a drug stored in a reservoir. The first aggregate is used for sensing and memory, and a second aggregation for control aspects, such as for pumping and dispensing of the drug. The system may communicate with a remote control system, or operate independently on local power over a long period for delivery of the drug based upon a request of the patient, timed-release under control by the system, or delivery in accordance with measured markers. See U.S. Pat. No. 6,464,687, incorporated herein by reference in its entirety.

EXAMPLES

The invention will be illustrated in more detail with reference to the following Examples, but it should be understood that the present invention is not deemed to be limited thereto.

Example 1: Typical Route from Manufacturer to Drug Release

The purpose is to illustrate how the above described system combine to have a secure, traceable and [as much as possible] safe delivery of the drug, for example a single pill dosage. The two pill dosages can be implemented and also “avoid” mixing drug schemes are envisaged.

The manufacturer doses the drug in the pill and activates it. This activity comprises several steps:

reads the pill ID and associate all the drug information to it in the database

enables the pill by issuing the enable security flag command enable F1 (P1,R1), which will change the status of the first security layer (flag). The pill will at first verify that the F0 is correct and only after apply the change as mandated by the multilevel security system policy.

The pills are sent to pharmacies. The database will register the pharmacies that received the pill.

The pharmacist prepares the prescription:

it uses a special terminal with unique TERM ID over the secure the communication network

reads the pill PID

obtains from the server a challenging-response (P1, R1)

issues a get F13-F15 (P1,R1) command to verify any tempering attempt.

the pill verifies first the F0 and then F1 to see if the pill was activated by the manufacturer as mandated by the multilevel security system policy; if correct it continues, otherwise it stops issuing an error message; if the F1 layer is enabled it computes the result R of M1 using S1 and P. If R is the same of R1, it considers the command legitimate, and returns F13-F15 if it didn't arrive to the maximum allowed number, otherwise issue a pill disabled due to tampering message which is sent to the manufacturer. In this case the pill becomes unusable.

after receiving the F13-F15 response the terminal obtains another challenging-response (P2, R2)

issues a enable F2 (P2,R2) command

the pill verifies first the F1 to see if the pill was activated by the manufacturer; if correct it continues, otherwise it stops issuing an error message; if the F1 layer is enabled it computes the result R of M1 using S1 and P2. If R is the same of R2, it considers the command legitimate, changes the status of F2 and issues an acknowledge message. The result is stored on the database.

Similar the terminal might issue an enable F3 command if a timer is envisaged. The logic follows the one described above. (see “Patient terminal” section).

If a user terminal is envisaged, the pharmacist will communicate the user's TERM ID to the manufacturer to be associated with the pill ID.

The user terminal will similarly exchange information with the pill and manufacturer and enable F3B security layer (first verifying the activation of F1, F2, F3 and the anti tempering counter F13-F15).

The pill gets ingested.

The sensors in the pill confirm that it was ingested (in the simplest case by temperature, liquid sensor and time). At this point it will initiate an over dose verification. If the result is ok will enable F12.

The drug release watch dog will verify the F0-F15 status and if it matches the expected result will enable the drug release command, and change the F0 to 0 (pill terminated).

While the invention has been described in detail and with reference to specific examples thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.
